(1) - 20V Power Share PRO 4.0Ah Lithium-Ion High-Capacity Battery

The POWER SHARE PRO series of WORX high-capacity batteries are designed for optimal performance and come standard with the WORX NITRO product offering. These batteries utilize an intelligent battery management system that monitors each cell to enhance, power, performance, and runtime. Innovative, thermoplastic material encases each cell to pull heat away and maximize the cell’s performance, resulting in longer runtime. 360° cell protection provides increased security against vibration, drops, and water intrusion. This full-wrap design limits the influence that a compromised cell can have over the rest of the battery pack.


POWER SHARE PRO batteries are 100% compatible with all WORX 20V, 40V, 80V tools, outdoor power, and lifestyle products that display the POWER SHARE or POWER SHARE PRO logo. Although the WORX POWER SHARE PRO high-capacity batteries come standard with WORX NITRO products, they can also be utilized on the traditional WORX products to achieve longer runtime. WORX recommends that POWER SHARE PRO batteries be used with WORX NITRO products to unlock optimal performance.

*NOTE: Although technically compatible, some new and discontinued tools may have a battery compartment that is too small in size to accommodate the WA3678 8ah battery (such as WG744 and Landroid).

No. The WORX POWER SHARE PRO batteries can be used on all existing WORX 20V MAX chargers (WA3742, WA3881, WA3764, WA3770, WA3884, WA3835).

No. The batteries require the same amount of charge-time as the standard WORX POWER SHARE batteries. However, due to the Cell-Cooling Technology in the POWER SHARE PRO batteries, they stay cooler, longer. As a result, less wait-time is needed before a battery can start charging, due to high temperature.
